IMPROVEMENT IN FASTENERS FOR THE MEETING-RAILS OF SASHES.

Specification forming part of. Letters Patent No. 199,194, dated January15, 1878 application filed December 10, 1877.

To all whom it may concern:

Be it known that 1, WILLIAM T. DOREMUS, of the city, county, and Stateof New York, have invented a new and useful Improvement in Sash-Stops,of which the following is a specification:

Figure 1 is a front view of my improved device. Fig. 2 is a verticalsection of the same, taken through the line a0 as, Fig. 1. Fig. 3 is atop view of the same. Fig. 4 is a detail under-side view of thecatch-bar.

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish improved stops or looks forwindow-sashes which shall be so constructed that they must be unfastenedbefore the sash can be opened, and which will fasten themselves as thesash is lowered, so that the sash cannot be lowered without being at thesame time fastened, thus guarding against the possibility of closing thewindow and leaving it unfastened.

The invention consists in the novel combination of the bent plate orframe, the pivoted latch, provided with one. or more shoulders ornotches in the lower part of its forward edge, and the catch-bar, witheach other, to adapt them to be attached to the rails of a windowsash;and in the combination of the long pin and the rigid collar or washerwith the bent plate or frame and the pivoted latch, to give the devicestrength to resist the momentum of the sash when being raised, all ashereinafter more fully described and claimed.

A represents the lower sash, and B the upper sash. When the device isattached to the bottom rail of the upper sash, as shown in Figs. 1, 2,and 3, or to the side rail of the upper sash, close to its bottom rails,the beveled rear edge of the top of the lower sash is cut away ornotched, to allow the device to be made thicker than is otherwisepossible, and the notch or space thus formed is filled by a-wedge-shaped block, D, which is secured to the beveled bottom rail ofthe top sash, as shown in Figs. 1, 2, and 3.

The frame E of the stop is formed of sheet metal, bent into U form, andis attached to the bottom rail of the upper sash, or to the lower partof the side rail of said upper sash. WVhen the device is attached to themiddle part of the bottomrail, the plate of the frame E is made wider,and strips 0 are cut out of its forward part-and turned downward atright angles with its base, so as to overlap the forward side of thewedge-block D, to which it is secured by screws. 1

To and between the upper ends of the arms of the frame E is attached apivot or pin, F,

to which is pivoted a latch, G. The latch G is made of such a lengththat its free end may strike against the base of the frame F, or againsta stop formed upon or attached to the lower part of said frame E. To thetop rail of the lower sash A is attached a catch-bar, H, the inner endof which projects, so as to be struck by the forward edge of the latchGr. In the forward edge of the latch G is formed a notch or shoulder toswing over the catch-bar H, and thus lock the window closed. The latch Gis beveled above the notch or shoulder, so that it may be pushed back bythe catch-bar H as the sash descends.

When the device is attached to the meetingrails of the sashes, theforward edge of the latch G has a second notch or shoulder formed uponit above the main notch, so as to lock the sash should it be prevented,by snow or ice or other cause, from descending quite to its place. Oneof these stops is designed to be attached to the side rail of the uppersash, six inches (more or less) from its lower end, so thatshould asneak-thief or other person attempt to raise a sash that has been leftpartly raised, the catch-bar Hwill strike against the shoulder or notchof the latch G, and the sash will be stopped before it has been raisedfar enough to admit him. a

When the device is attached to the side bar of the upper sash, the pin Fis made long and large, so that it may enter a hole in the said siderail to hold the said device in place, and give it strength to resistthe momentum of the lower sash when it is pushed up with force. In thiscase, for convenience in manufacture, the pivot or pin F has a collar orwasher formed upon or attached to it, so as when the latch G has beenput upon it, and the ends of the bent plate or frame E sprung upon it,the said pin will not need to be riveted or further secured to the saidframe.

When the device is attached to the middle parts of the sash-rails, apart, J of the forward part of the plate or frame E is made V- shaped;or a separate V-shaped strip is attached to the block A, or to thesash-rail, and a hole beveled upon the inner side is formed through theforward end of the catch-bar H, so as, when the window is closed, todraw the meeting-rails of the sashes snugly together.

With this construction the sash can only be opened by turning the latchG back away from the catch-bar H. The latch Gr may be turned backwardand upward past a perpendicular, and left there, being kept from turningtoo far by a stop formed upon the frame E, against which it strikes, orby a pin attached to it to strike against the said frame E, or by havinga notch or shoulder formed in it to strike against the collar or washer.Then, as the sash is raised, the catch-bar H will strike against thesaid latch G and turn it back, ready to fasten the window when the sashis again lowered.

Vith this construction the window cannot be closed without beingfastened, unless the latch G be turned back purposely after 1owering thesash.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. The combination of the bent or U shaped plate orframe E, the pivoted latch G, pro vided with one or more shoulders ornotches in the lower part of its forward edge, and the catch-bar H, witheach other, to adapt them. to be attached to the rails of a window-sash,substantially as herein shown and described.

2. The combination of the V-shaped strip J and the catch-bar H, providedwith a beveled hole in its inner end, with each other, for drawing themeeting-rails of the sashes together when the window is closed,substantially as herein shown and described.

WILLIAM T. DOREMUS.
